... subjected to a UV irradiation treatment at 200°C in order to elec- trically passivate carbon-related defect states at the sur- face [9,10]. Front contacts were formed by sputt er deposition of a 100-nm-thick ... low-barrier patches of about 0.5-1.5 μm in diameter. Clearly, the evolution of these low-barrier patches will affect the properties of the fabricated diodes. Indeed, the e...
